TITLE

Cisco IOS XR Software MPLS Packet Handling Denial of Service Vulnerability

Trust: 0.9

sources: CNVD: CNVD-2014-04458 // BID: 68536

DESCRIPTION

Cisco IOS XR 4.3.4 and earlier on ASR 9000 devices, when bridge-group virtual interface (BVI) routing is enabled, allows remote attackers to cause a denial of service (chip and card hangs) via a series of crafted MPLS packets, aka Bug ID CSCuo91149. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. A denial of service vulnerability exists in Cisco IOS XR Software MPLS packet processing, allowing an attacker to exploit a vulnerability to initiate a denial of service attack. Cisco IOS XR is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause the affected device to crash, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCuo91149
